Hi,
I am using Sid on my laptop (HP ZBook 15) and since first linux-image-5.2.0-1 and then linux-image-5.2.0-2
the wifi is not stable and goes down after few seconds.
But what is more strange is that with linux-image-5.2.0-1 there is a log trace of the trouble but not with linux-image-5.2.0-2.
Here is an extract of the log using first package 5.2.0-1:
